Tomato blight last year, what to do with stakes?

Our garden was hit badly with tomato blight last year. We have moved the location this year to avoid this. Naturally, we have a number of stakes we used to support last year's plants, can we reuse these without spreading blight? Is there a cleaning process required?

Maybe you can re-use the stakes if you mix up a bit of fungicide in a container and scrub the stakes with them,,,,are the stakes wooden?,,,as wooden stakes may harbor the blight in them even with scrubbing.
